Description

Technical Field

[0001] This utility model relates to the field of biomass pelleting technology, and in particular to a biomass pelleting machine structure that facilitates quick replacement of the die plate. Background Technology

[0002] A biomass pellet mill is a specialized piece of equipment that processes biomass raw materials such as straw, sawdust, and rice husks into high-density pellet fuel through an extrusion molding process. The biomass pellets produced by the mill have the characteristics of high combustion efficiency, convenient storage and transportation, and low pollution. It is a key piece of equipment for realizing the efficient utilization of biomass resources and promoting the development of clean energy.

[0003] Traditional biomass pellet mills mainly consist of a feeding system, a conditioning system, a pelletizing system, a transmission system, and auxiliary systems. The feeding system uses an auger to transport raw materials to the conditioning system. The conditioning system humidifies and heats the raw materials by introducing steam, improving their plasticity. The pelletizing system, as the core component, consists of a ring die, pressure rollers, a main motor, and a transmission mechanism. The conditioned raw materials are squeezed into the forming holes of the ring die by the relative rotation and extrusion of the ring die and pressure rollers, forming strip-shaped pellets, which are then cut to a set length by a cutter. The transmission system provides power to the equipment through a motor and gearbox. However, traditional pellet mills have many drawbacks during use: uneven feeding leads to fluctuations in equipment load, unstable conditioning effects affect pellet forming quality, and the overall structure is bulky and difficult to maintain.

[0004] To address the aforementioned issues, existing technologies improve feeding uniformity by optimizing the spiral structure of the feeding auger, enhance raw material conditioning by employing a multi-stage conditioner, and improve gear meshing accuracy in the transmission system to reduce energy consumption and noise. However, in actual production, the die plate, a core consumable component, needs frequent replacement based on raw material characteristics or pellet specifications. Existing pellet mills typically use traditional fixing methods such as bolt fastening or flange connection for the die plate, requiring the disassembly of multiple fasteners during replacement. This process is cumbersome and time-consuming, severely impacting production continuity and increasing downtime costs. Therefore, achieving rapid and convenient die plate replacement has become a key challenge for existing biomass pellet mills. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a biomass pellet mill structure that facilitates quick replacement of the die plate, aiming to improve the problem that the replacement of the die plate in the prior art requires the disassembly of multiple fasteners, which is cumbersome and time-consuming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a biomass pellet mill structure that facilitates quick replacement of the die plate, comprising a ring die, a rotating disk rotatably connected to the bottom of the ring die, a base plate rotatably connected to the outer wall of the rotating disk, a fixing frame provided at the bottom of the base plate, a quick-release mechanism provided at the bottom of the rotating disk, and a cleaning mechanism provided at the top of the rotating disk. The quick-release mechanism includes multiple connecting rods, one end of each connecting rod is rotatably connected to the middle of the bottom of the rotating disk, and the other end of each connecting rod is provided with a limit component. A drive cylinder is fixedly connected to the left side of the inner wall of the chassis, and a connecting rod is fixedly connected to the output end of the drive cylinder. A fixing block is rotatably connected to the middle of the outer wall of the connecting rod, and a locking component is provided at the top of the limit component.

[0007] As a further description of the above technical solution: The cleaning mechanism includes a bearing, the outer wall of which is rotatably connected to the middle of the inner wall of the rotating disk. A rotating shaft is rotatably connected to the inner wall of the bearing. A motor is fixedly connected to the top of the fixed frame. The output end of the motor is fixedly connected to the bottom end of the rotating shaft. Rotating rods are fixedly connected to the front and rear sides of the upper part of the outer wall of the rotating shaft. Scrapers are fixedly connected to the opposite sides of the two rotating rods.

[0008] As a further description of the above technical solution: The limiting component includes multiple sliders, the bottom ends of which are fixedly connected to the top of the corresponding fixed block. Multiple slide rails are provided around the top of the outer wall of the chassis, and the outer walls of the multiple sliders are slidably connected to the inner walls of the corresponding slide rails.

[0009] As a further description of the above technical solution: The locking component includes multiple locking blocks, the bottom ends of which are fixedly connected to the top ends of the corresponding sliders. Each of the multiple locking blocks has a locking post fixedly connected to an adjacent side. The lower part of the outer wall of the ring mold has multiple locking slots, and the multiple locking posts engage with the corresponding locking slots.

[0010] As a further description of the above technical solution: Oil storage grooves are provided on the left and right sides of the inner walls of the multiple slide rails, and rubber sleeves are fixedly connected to the inner walls of the multiple oil storage grooves.

[0011] As a further description of the above technical solution: The bottom of the chassis is fixedly connected to a mounting plate, and the outer wall of the mounting plate is threaded with multiple screws.

[0013] As a further description of the above technical solution: Rotating rods 2 are fixedly connected to the left and right sides of the outer wall of the rotating shaft, and scrapers 2 are fixedly connected to the outer walls of the two rotating rods 2.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the connecting rod drives the fixing block to link multiple connecting rods, thereby driving the limiting component to slide along a preset trajectory. The limiting component simultaneously drives the locking component's locking part to engage or disengage with the ring mold's slot. This structure does not require disassembling fasteners and can complete the locking and unlocking of the ring mold simply by using a cylinder drive. This solves the problem of cumbersome and time-consuming replacement in the prior art and significantly improves replacement efficiency.

[0015] 2. In this utility model, by cooperating the outer wall of the bearing in the cleaning mechanism with the inner wall of the rotating disk and rotating the inner wall with the rotating shaft, the movement isolation between the quick-release mechanism and the cleaning mechanism is achieved. The motor drives the rotating shaft to rotate, which drives the rotating rod and scraper to rotate synchronously. The scraper scrapes against the inner wall of the ring die. This structure can remove the material residue accumulated around the inner hole of the ring die in real time, solving the problem in the prior art that the material residue blocks the die hole, causing the pelleting efficiency to drop and requiring frequent shutdowns for manual cleaning.

The top of the rotating disc 4 is provided with a cleaning mechanism 3 to remove material residue buildup inside the ring die 1 during granulation, preventing die hole blockage. The quick-release mechanism 2 includes multiple connecting rods 201 for transmitting power, evenly transmitting the force on the rotating disc 4 to the limiting component 202, ensuring... To ensure the synchronicity of the quick-release action, one end of each of the multiple connecting rods 201 is rotatably connected to the bottom center of the rotating disk 4 via a pin, allowing the connecting rods 201 to rotate flexibly relative to the rotating disk 4 and adapt to the movement requirements of the quick-release mechanism 2. The other end of each connecting rod 201 is equipped with a limiting component 202 to restrict the movement trajectory, ensuring that each component of the quick-release mechanism 2 moves along a preset trajectory and preventing jamming or deviation. A drive cylinder 203, serving as the power source for the quick-release mechanism, is bolted to the left side of the inner wall of the chassis 5, providing linear driving force to drive the quick-release mechanism 2 to complete the locking and unlocking actions. The output end is connected to a connecting rod 204 for transmitting power via a threaded connection, which transmits the power of the drive cylinder 203 to the fixed block 205, realizing the transfer of power.

The top of the limiting component 202 is provided with a locking component 206 for locking and fixing the ring die 1, which realizes the reliable fixing of the ring die 1 through mechanical engagement, preventing the ring die 1 from loosening or displacing during the granulation process. Specifically, the ring die 1, as the core component of granulation, provides the die cavity carrier. Its bottom is rotatably connected to the rotating disk 4 via bearing 301. The rotating disk 4 carries the ring die 1 and enables its stable rotation. The outer wall of the rotating disk 4 is rotatably connected to the base 5 via bearing 301.

The cleaning mechanism 3 at the top of the rotating disk 4 removes material residue from the ring die 1 to prevent blockage. Multiple connecting rods 201 in the quick-release mechanism 2 transmit power, evenly transmitting the force on the rotating disk 4 to the limit component 202 to ensure synchronous quick-release action. One end of the connecting rod 201 is connected to the base 5 via a pin. The rotating disk 4 is rotatably connected at the bottom center, allowing for flexible rotation to adapt to movement requirements. The limiting component 202 at the other end of the connecting rod 201 restricts the movement trajectory, ensuring that the component moves along the preset trajectory to avoid jamming or deviation. The drive cylinder 203 on the left side of the inner wall of the chassis 5 is fixed with bolts to provide linear driving force, driving the quick-release mechanism 2 to complete locking and unlocking. The output end of the drive cylinder 203 transmits power to the fixed block 205 through the threaded connecting rod 204 to achieve power transfer. The fixed block 205, which is rotatably connected to the outer wall of the connecting rod 204 through the bearing 301, is linked to the limiting component 202 to convert linear motion into coordinated motion to ensure consistent action. The locking component 206 at the top of the limiting component 202 securely fixes the ring mold 1 through mechanical engagement, preventing loosening or displacement during granulation.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The cleaning mechanism 3 includes a bearing 301 for relative rotational isolation, ensuring that the movements of the quick-release mechanism 2 and the cleaning mechanism 3 do not interfere with each other and guaranteeing the independence of their respective actions. The outer wall of the bearing 301 is rotatably connected to the middle of the inner wall of the rotating disk 4 via an interference fit, providing a stable mounting base for the bearing 301 and ensuring its load-bearing capacity and rotational accuracy. The inner wall of the bearing 301 is rotatably connected to a rotating shaft 303 for transmitting torque via a clearance fit, transmitting the power of the motor 302 to each actuator to realize the power output of the cleaning action. The top of the mounting bracket 10 is fixedly connected to the motor 302, and the output end of the motor 302 is connected to the rotating disk 4. The bottom end of the rotating shaft 303 is fixedly connected to provide continuous and stable rotational power for the cleaning mechanism 3, driving the entire cleaning mechanism 3 to operate. The upper front and rear sides of the outer wall of the rotating shaft 303 are fixedly connected by welding to the rotating rod 304 for installing the scraper, which transmits the rotational motion of the rotating shaft 303 to the scraper 305, while ensuring that the relative position of the scraper 305 and the rotating shaft 303 is fixed. The two rotating rods 304 are fixedly connected by bolts to the scraper 305 for scraping the material residue on the inner wall of the ring die 1. By scraping against the inner wall of the ring die 1, the material residue accumulated around the inner hole is removed in time to prevent the die hole from being blocked. Specifically, the bearing 301 of the cleaning mechanism 3 achieves relative rotational isolation, ensuring that the quick-release mechanism 2 and the cleaning mechanism 3 do not interfere with each other and that their respective actions are independent. The outer wall of the bearing 301 is rotatably connected to the middle of the inner wall of the rotating disk 4 through an interference fit, providing a stable mounting base for the bearing 301 to ensure load-bearing capacity and rotational accuracy. The inner wall of the bearing 301 is rotatably connected to the rotating shaft 303 through a clearance fit. The rotating shaft 303 transmits torque to transmit the power of the motor 302 to each actuator to realize the power output of the cleaning action. The motor 302 at the top of the mounting bracket 10 serves as the power source for the cleaning mechanism. 3 provides continuous and stable rotational power to drive the entire cleaning mechanism 3 to operate. Rotating rods 304 are fixedly connected to the upper front and rear sides of the outer wall of the rotating shaft 303 by welding. Rotating rods 304 are used to install scrapers to transmit the rotational motion of the rotating shaft 303 to scrapers 305 and ensure that scrapers 305 and rotating shaft 303 are fixed in relative position. Scrapers 305 are fixedly connected to the two rotating rods 304 on the side away from each other by bolts. Scrapers 305 are used to scrape off the material residue on the inner wall of the ring mold 1. By scraping against the inner wall of the ring mold 1, the material residue accumulated around the inner hole is removed in time to prevent the mold hole from being blocked.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The limiting component 202 includes multiple sliders 2021 for linear sliding, providing a motion carrier for the locking component 206 and ensuring the linearity of the locking action. The bottom ends of the multiple sliders 2021 are respectively fixedly connected to the top ends of corresponding fixing blocks 205. The driving cylinder 203 drives the fixing blocks 205 to move the sliders 2021 in conjunction. Multiple slide rails 2022 are provided around the top of the outer wall of the chassis 5 to limit the movement trajectory, constraining the sliding direction of the sliders 2021 and preventing radial displacement. The outer walls of the multiple sliders 2021 are slidably connected to the inner walls of the corresponding slide rails 2022. Through sliding cooperation, the sliders 2021 move directionally along the slide rails 2022, ensuring the smoothness of the movement. The locking component 206 includes multiple pins 2062 for connecting the sliders 2021 and the locking posts 2062. The locking block 2061 transmits the power of the slider 2021 to the locking post 2062 to achieve linkage action. The bottom ends of multiple locking blocks 2061 are fixedly connected to the top ends of the corresponding sliders 2021, so that the locking blocks 2061 and the sliders 2021 form an integral structure to ensure that the power transmission is smooth. The adjacent sides of multiple locking blocks 2061 are fixedly connected to locking posts 2062 for locking, which serve as locking actuators and achieve mechanical cooperation with the slots 2063. Multiple slots 2063 for locking are opened on the lower part of the outer wall of the ring mold 1, providing locking positions for the locking posts 2062 and forming locking fulcrums. Multiple locking posts 2062 are respectively locked with the corresponding slots 2063, and the ring mold 1 and the chassis 5 are fixed relative to each other through mechanical locking action to prevent the ring mold 1 from axial or radial displacement during operation. Specifically, the multiple sliders 2021 of the limiting component 202 achieve linear sliding, providing a motion carrier for the locking component 206 to ensure the linearity of the locking action. Multiple slide rails 2022, formed around the top of the outer wall of the chassis 5, define the motion trajectory and constrain the sliding direction of the sliders 2021 to prevent radial deviation. The outer walls of the multiple sliders 2021 are slidably connected to the inner walls of their respective slide rails 2022. Through sliding cooperation, the sliders 2021 move directionally along the slide rails 2022, ensuring stable movement. Multiple locking blocks 2061 of the locking component 206 connect the sliders 2021 to the locking posts 2062, transmitting the power of the sliders 2021 to the locking posts 2062. In the current linkage action, the bottom ends of multiple locking blocks 2061 are fixedly connected to the top ends of corresponding sliders 2021, so that the locking blocks 2061 and sliders 2021 form an integral structure to ensure that the power transmission is smooth. The slide rails 2022 fixedly connected to the adjacent sides of multiple locking blocks 2061 serve as locking actuators, achieving mechanical cooperation with the locking slots 2063. Multiple locking slots 2063 opened on the lower part of the outer wall of the ring mold 1 provide locking positions for the locking posts 2062 to form locking fulcrums. Multiple locking posts 2062 are respectively locked with the corresponding locking slots 2063. Through the mechanical locking action, the ring mold 1 and the chassis 5 are relatively fixed to prevent axial or radial displacement of the ring mold 1 during operation.

[0022] Reference Figure 1 , Figure 2 and Figure 3 Multiple slide rails 2022 have oil reservoirs 6 on their inner walls on both the left and right sides for storing lubricating oil, providing a lubricating medium for the sliding engagement between the slider 2021 and the slide rails 2022. Rubber sleeves 7 are fixedly connected to the inner walls of the multiple oil reservoirs 6 for sealing and oil extrusion. The lubricating oil is evenly extruded by the extrusion of the slider 2021, ensuring lubrication. A mounting plate 8 for connecting to the granulator machine tool is fixedly connected to the bottom of the chassis 5, providing an installation interface for the entire structure. Multiple screws 9 are threaded around the outer wall of the mounting plate 8 for fixing it, reliably connecting the mounting plate 8 to the machine tool through threaded fastening. The top left side of the chassis 5 is fixedly connected to... The heat sensor 14 is connected to the chassis 5. The heat sensor 14 is used to detect the temperature of the ring mold 1 and the motor 5. Multiple heat dissipation holes 11 are opened around the outer wall of the chassis 5 to dissipate heat. The heat generated by the motor 302 and surrounding components is carried away by air circulation to avoid overheating and damage to the components. Rotary rods 13 for mounting scrapers 12 are fixedly connected to the left and right sides of the outer wall of the rotating shaft 303. The rotation power of the rotating shaft 303 is transmitted to the scrapers 12. Scrapers 12 for cleaning the material residue at the bottom of the ring mold 1 are fixedly connected to the outer walls of the two rotating rods 13. The material residue accumulated at the bottom of the ring mold 1 is removed by rotating and scraping to prevent the bottom residue from clogging the mold hole. Specifically, oil reservoirs 6 are formed on the left and right sides of the inner walls of multiple slide rails 2022 to store lubricating oil, providing a lubricating medium for the sliding cooperation between the slider 2021 and the slide rails 2022. Rubber sleeves 7 are fixedly connected to the inner walls of the oil reservoirs 6 to seal and squeeze out the oil. The lubricating oil is evenly distributed by the slider 2021 to ensure lubrication. A mounting plate 8 is fixedly connected to the bottom of the chassis 5 to the granulator machine tool, providing an installation interface for the entire structure. Multiple screws 9 are threaded around the outer walls of the mounting plate 8 to secure it, ensuring a reliable connection between the mounting plate 8 and the machine tool, guaranteeing proper operation of the motor 302. To ensure stability, thermal sensor 14 is used to detect the temperature of ring die 1 and motor 5. Multiple heat dissipation holes 11 are opened around the outer wall of chassis 5 to dissipate heat. The heat generated by motor 302 and surrounding components is carried away by air circulation to prevent overheating and damage to components. Rotating rods 13 fixedly connected to the left and right sides of the outer wall of rotating shaft 303 are equipped with scrapers 12 to transmit the rotation power of rotating shaft 303 to scrapers 12. Scrapers 12 fixedly connected to the outer walls of the two rotating rods 13 clean the material residue at the bottom of ring die 1. The material residue accumulated at the bottom of ring die 1 is removed by rotating and scraping to prevent the bottom residue from clogging the die hole.

[0023] Working principle: When replacing ring die 1, first press the control switch to start the drive cylinder 203. The piston rod of the drive cylinder 203 extends outward, pushing the connecting rod 204 to move linearly. The connecting rod 204 drives the fixed block 205 connected to it to move synchronously, thereby driving the slider 2021 to slide along the track of the slide rail 2022. The slide rail 2022 plays a precise limiting role, ensuring that the slider 2021 always moves along the preset trajectory, avoiding structural jamming caused by deviation. As the slider 2021 slides outward, the original locking state is released, and the operator can directly remove the old ring die 1. The new ring die 1 is aligned with the installation position and placed stably. After the new ring die 1 is placed in place, press the switch again to control the drive cylinder 203 to retract. The piston rod pulls the connecting rod 204 to move in the opposite direction, and the fixed block 205 moves accordingly. Block 2021 resets inward along slide rail 2022. During the reset process, slider 2021 simultaneously drives the locking post 2062 on the side of locking block 2061 to accurately insert into the slot 2063, completing the quick locking of ring die 1. At the same time, when slider 2021 slides on the inner wall of slide rail 2022, it will squeeze rubber sleeve 7. After being compressed, rubber sleeve 7 squeezes out the lubricating oil in oil storage tank 6, forming a uniform oil film on the contact surface between slider 2021 and slide rail 2022, realizing the self-lubrication of sliding structure. In addition, mounting plate 8 and screw 9 securely install the entire quick-release structure on the pellet mill machine tool. Fixing bracket 10 is used to fix motor 302. Thermal sensor 14 is used to detect the temperature of ring die 1 and motor 5. Heat dissipation hole 11 dissipates heat for motor 302 through air circulation, avoiding overload damage to motor 302 during long-term operation. After the ring die 1 is installed, when the pressure roller is working, some material residue will accumulate around the inner hole of the ring die 1. At this time, the motor 302 starts and drives the rotating shaft 303 to rotate. Due to the isolation effect of the bearing 301, the quick release mechanism 2 and the cleaning mechanism 3 do not interfere with each other, ensuring their stable movement. The rotating shaft 303 synchronously drives the rotating rod 304 to rotate, so that the two scrapers 305 connected to the rotating rod 304 are in contact with the inner wall of the ring die 1 to scrape in a circular motion, promptly removing the material residue accumulated around the inner hole and preventing it from clogging the die hole. At the same time, the scraper 12 installed on the rotating rod 13 rotates synchronously with the rotating system, specifically scraping away the material residue accumulated at the bottom of the ring die 1, avoiding the formation of stubborn accumulation of material at the bottom. Through the synergistic action of scraper 305 and scraper 12, the residual material residue in the ring die 1 can be completely removed, solving the problem of die hole clogging and reduced granulation efficiency caused by material residue accumulation in the traditional granulation process.
